pcm-memory:mainloop: Always flush cout

[bsdimp]

Flushing cout in cvs mode is also useful when the output is a pipeline using the values to display in real time. As such, always flush the cout buffers at the start of the main loop.

thanks for the patch, this is useful. But to reduce the overhead for non-interactive mode when sampling with a higher frequency the flushing should be avoided in csv mode. The flushing should be optional like in pcm-iio: https://github.com/opcm/pcm/blob/58039287e0ee63edcaa60bdbf837d536e4e417da/src/pcm-raw.cpp#L74 Could you please implement it similarly?
